" MAH'E FA'JTURE OF STEEL.

Specification of Letters Patent.

Patented Oct. 27, 1908.

Application filed January 9, 19138. Serial No. 409,968.

To all whom it concern:

Be it known that we, Sis SrArLnroRn and JAMES F. WAGNER, citizens of the United States, residing at Aberdeen, in the county of Chehelis and State of Washington, have invented certain new and useful improvements in the lilenufccturc of Steel, of which the following is a specification.

Our invention consists in the production, manufacture and of the following forrnule for extracting, purifying and producing iron and steel, and especially the insnulacturc of's high grade of steel for use in the manufacture of line instruments rind tools, and we do hereby. declare the following to be it full, clear and exact description of the some. I

In the reduction of magnetic oxid of iron, or magnetic iron sand, wcuse the following formula to make a. given quantity, viz ine netic oXJid of iron or sencs, iOO pounds; pu verized charcoal (damp), 80 pounds; bicarbonate of soda, 12 pounds pulverized boreX, 8 pounds.

The above quantity of the diilercnt ingreclients is to be thoroughly mixed into a thick paste with silicate of soda; this can be mode into briclrswith o briqucting machine, or can be made by hand if desired and must be dried in an. oven, and then can be reduced in a common cupole or blast furnace, and can also be reduced in a, crude oil furnace.

' Though We have mentioned, in our composition, magnetic oxirl of iron or sands, we are able by our process to extract steel also from the magnetic iron particles separated therefrom, or from metallic ore dust (irony inetallic residues.

W e do not Wish to be understood as confin- 49 ing ourselves to the quantities above Ill-31btioned, but to the proportions.

Having described our invention, whet claim as new and desire to secure by Letters Patent, is

, 1. The process of extracting, purifying and 415 producing iron and steel, which consists in using magnetic oXid of iron or send, 100 pounds; pulverized charcoal, clamp, 80 pounds; bicarbonate of soda 12 pounds; pulverized borex, 8 pounds, or the some ingre- 5 (lients in like proportions, the above ingrcdie ents being thoroughly mixed into it thick paste with silicate of soda, and made into bricks, dried in an oven and then reduced in e metallurgical furnace, substantially as de-- scribed.

2. The process of making steel from mag-- netic oxid of iron or sends, which consists in mixing said magnetic oxid of iron or sends with damp pulverized charcoal, bicarbonate so of soda and pulverized borsx, into a. thick paste with silicate of soda, drying'in an oven, 7 and then extracting therefrom the steel by the melting process in a crude oil furnace, substantially as described.

3. The process of Winning metals from magnetic iron, sand, or from magnetic perti-= cles separated therefrom, or from metallic iron ore, dust or from any metallic residues, which consists in mixing the said materials with pulverized charcoal, bicarbonate of sods and pulverized borex, forming from the mass bricks, and extracting therefrom the materials by furnace process, substantially described and set forth.

In testimony whereof we effix our signstures in presence of two Witnesses.
